RYEFRIGERATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 275,556, dated April 10, 1883.

v Application tiled December 1S, 1882. (No model.)

`l'o all 'whom it may concern Be it knownthat I, GEORGER. WIGHT, o New York, in the county and State of New York, have invented a certainnew and use-I ful Improvement in Refrigerative Apparatus, of which the following is a specification.

This improvement relates to apparatus which is employed as a iixture in buildings.

The improvement will be described in de tail, and then pointed out in the claims.

. In the accompanying drawings, Figure l is a vertical section ota building embodying my improvement. Fig. 2 is an enlarged view of a portion of the rei'rigerative apparatus, and Fig. 3 isa sectional view illustrating a refrigerating apparatus of modified form.v4

Similar letters of reference desi gnate corresponding parts in all the gures.

A designates the upper door of a building, and A A2 A3 A4 designate the several doors below it.

In the upper door is a ret'rigerating apparatus, consisting of one or more ice-tanks, a, and a number of isolated pipes, b, communieatin g therewith at the upper ends. The tank or tanks and the pipes may be made ot' galvanized sheet-iron. The lower ends of the pipes rest 011 a grating, c, which may be made of wood or other suitable material, and as they are open the ice contained therein will be supported upon the grating.

Below the grating are drip-pans d, which catch the water formed b v the melting of the ice. These drip-pans may be slid out from under the grating, if desirable, or they may be provided with drain-pipes for carrying off the water. The pipes b are provided with feet b', which extend through the grating c and are'supported on the drip-pans. The pipes b are provided with small inner pipes, d, or groups "of rods, for maintaining passages through which air -may circulate within the ice in the said pipes b. .y

A platform, c, is arranged over the ice-tanks and. provided with openings, through which ice can be introduced into the tanks a. Persons whose duty it is to fill-the tanks may walk or crawl over this platform.

v At the lower ends the pipes b have side openings, b2, and are iitted with annular doors b3, which normally rest on the grating c, but

may be slid up on the pipes to uncover the openings., These doors Vare provided with eyes b4, which may be slipped over hooks b5, valixed to the pipes, b, to support the doors. Access is thus afforded to the lower ends of the pipes for the purpose of cleaning them out.

Duets or passages ff j'zfs extend from the bottom portion ot' the door A to the bottom I portions ot' the iioors'A A2 A3 A* below.

Other ducts, e e e2 e3, extend from the top portion ofthe floors A A2 A3 A4 to the top portion of the door A. The cool air in the bottom portion of the oor A descends to the bottom portion ,of the floors A A2 A3 A4, and the warmer air in the iioors Al A2 A3 A4 passes tion of the floor A.

The inner walls of the ducts or passages f f fif3 and e c c'Z c3 are preferably covered with felt or other material which is a good non-conductor of heat, so that the temperature of the air passing through them shall be maintained until it arrives 'at the iioors where it is to be delivered and utilized.

The upper ends of the duct-s or passages are provided with doors g, which are shown as hinged in place, and serve to control and regnlate the passage of air between the iioors A A A2' A3 A4.

The refrigerating apparatus shown in Fig. 2 differs from that already described in that it consists of a number of isolated cage-like receptacles, b.

Whatl claim as my invent-ion, and desire to secure by Letters Patent, is-

l.. The combination, with a building, ofducts or passages leading from the bottom portion of an upper floor to the bottom portion of several floors below, other ducts or passages leading from the top portion of the lower iioors to the top portion of the upper floor, anda refrigeratng apparatus arranged on the upper door and comprising a number ot' ice-receptacles arranged at such distances apart that air may circulate freely between them, and so constructed that air may pass through them, substantiallyfas specified.

2. The combination, with a building, ofducts or passages leading from the bottom portion of an upper floor to the bottom portion of sevfrom the top portion thereof to the top por- IOC eral floors below, other ducts or passages leading from the top portion of the lower floors to the top portion of the upper floor, and a refrigerating apparatus arranged on the upper floor, and consisting of an ice tank or tanks and a number of pipes extending downwardly therefrom nearly to the floor, containing ice, and so constructed that air may pass downwardly through them in contact with the ice contained in them, substantially as specified. 3. The combination, with a building, of ducts or passages leading from the bottom portion of au upper Hoor to the bottom portion of several oors below, other ducts or passages leading from the top portion of the lower floors to the top portion ofthe upper Hoor, a refrigerating apparatus arranged on the upper door, and felt or other material which is a good non-conductor of heat applied to the inner walls of the ducts or passages, substantially as specified.

4. The combination, with a building, of ducts or passages leading from the bottom portion ot an upper floor to the bottom portion of several floors below, other ducts or passages leading from the top portion of the lower oors to top portion ot' the upper iioor, a refrigerating apparatus arranged on the upper floor, and a platform over this apparatus on which persons may walk or more when filling the apparatus, and which is providedwith openings, through which ice may be introduced downwardly in to the apparatus, substantially as specified.

5. The combination, with a building, of ducts or passages from the bottom portion of an upper floor to the bottom portion of several floors below, other ducts or passages leading from the top portion of the lower floors to the top portion of the upper floor, arefrigerating apparatus on the upper tioor,comprising a lininber of isolated ice-receptacles open at the lower end, a grating below thelower ends of the icereceptacles, serving to support the ice therein, and one or more drip-pans arranged below the grating, lsubstan tially as specified.

6. In a refrigerating apparatus, tho combination, with a number of isolated pipes having openings in their sides, ot'anuular sliding doors fitted thereto, substantially as specified.

7. In a refrigerating apparatus, the combination, with a number of isolated pipes having openings in their sides and provided with feet, of a grating for supporting ice in said pipes,a drip-pan below the grating serving to sustain Vthe feet of the pipes, and annular doors applied to the pipes and serving to control access to their openings, substantially as specified.
